摘要: Abstract As a new class of glycosyl donors, hydroquinone glycosides can be used for glycosylation reactions. Their activation performed either electrochemically or under homogeneous chemical conditions. Conventionally, several glucosides were produced with yields greater than 77% using DDQ in CH 2 Cl as oxidizing agent. For electrolyses, trimethylhydroquinone are preferably because their low oxidation potentials allow the utilization an undivided cell. The synthesis donors was achieved high efficiency by direct coupling phenols peracetylated monosaccharides employing boron trifluoride etherate catalyst. derivatives also applied to generation other stabilized cations.
